Ok, time for a chuckle here. I love reading all the different responses and love different views. But what I love the most is how passionate people are about their resort of choice, so much so that response are tailored to the OP's wants.
For the record, I would recommend CN,. based on your desires for "chill, r & r" and the quieter of the two.
Depending on where you are looking, such as TA you will find that most people think that CSA is more lively and that the crowd is younger.
We have only done a trading spaces with CSA, we liked what we saw and have decided that is where we are going this year. But I did think that the crowd was a little younger then we saw at CN. And the over all activity seemed to be a little higher. But as I said we liked enough to plan on staying there this year.
Before you criticize someone, walk a mile in their shoes. If they get mad, you will be a mile away and they will be barefoot!
